    Abstract

    Combustion engine power plant related technologies play a significant role in the energy industry. Today, global challenge over whole energy field is to reduce greenhouse gas emissions to combat climate change. This can be achieved by increasing energy efficiency, and by finding alternative and renewable options instead of conventional fossil energy sources. Work on fuel flexibility was conducted within the Future Combustion Engine Power Plant programme (FCEP) of the Cluster of Energy and Environment (CLEEN) in Finland. A number of fuel options, including challenging liquid biofuels and their treatment, as well as gaseous fuels, were explored for different engine concepts. LNG was found to be potential solution to oncoming environmental requirements in shipping. Biogas was studied as regards upgrading technologies, particularly siloxane removal, which is a weak spot for biogas from wastewater and landfills. Mediumspeed engine was tested by using different fuels. Some of the fuels were challenging, and therefore pre-treatment methods for difficult fuels were developed to enable their use in medium-speed engines. Combustion properties of various fuels were studied with special ignition test unit, with a medium-speed and with a high-speed engine. Some fuels yielded promising results when engine performance and emissions are considered. A special task devoted to development of a diesel-ignited dual fuel ethanol high-speed engine for non-road machinery. The developed engine can be switched from diesel to diesel-ethanol operation at any load without noticeable change in engine operating point. Work on fuel flexibility within the FCEP programme took steps towards increased fuel flexibility, and consequently, towards better energy security in Finland. In addition, the demand for lower environmental impact of the current combustion engines was sought for. The structure and form of FCEP programme supported close cooperation of the industrial and research partners. This kind of cooperation and further development in the field of fuel flexibility is still needed.
